BV Steel Sale

Gnee steel factory is approved by Bureau Veritas to produce AH, DH, and EH grade shipbuilding steel plates, adherence to chemical composition and mechanical properties as per NR216 rules. Extensive testing is carried out using state-of-the-art facilities and each board is stamped with BV along with traceable heat number. More than 15 years of production experience. Worldwide availability at very competitive prices.

Bureau Veritas (BV) is a classification society that sets standards for the marine industry.
Common BV grades for shipbuilding steel plates include AH32, DH32, EH32, AH36, DH36, and EH36. BV shipbuilding steels need to meet requirements such as impact tests at specified temperatures to ensure adequate toughness. They also must comply with requirements for chemical composition.
All BV shipbuilding steel needs to be produced at approved mills with qualified manufacturing procedures. Mills are regularly audited by BV surveyors.
During ship construction, BV inspects the steel plate marking, checks material certificates, witnesses steel cutting and welding, and reviews non-destructive testing records.
Using BV-approved shipbuilding steel is important to ensure mechanical strength, corrosion resistance, and weldability for the marine environment. Proper documentation verifies the quality of the steel plate.
